Application filed January 4,1900. Serial No. 378 (No model.)

' and I do hereby declare the following to be a illustrate one form inwhich I have contem' plated embodying my invention, and said inventionis fully disclosed in the following description and claims.

Fig. 9 is a perspective viewof a portion of the main frame and the casting for supporting one of thepivoted axles. Fig. 10 is an enlarged view of one of the elevating anddepressing levers and adjacent parts. Fig. 11 represents a horizontalsection on line 11 11 of Fig. 10. Fig. 12 is a front view of the devicesshown in Fig. 10.

My invention is designed to provide a cultivator having all theadvantageous features of a pivot-axle cultivator of improved design andconstruction and in which the axles can be looked when desired and thecultivators controlled directly by means of stirrups secured thereto andadapted to be engaged by the feet of the operator.

The main frame of the machine is composed of a series of bars bolted orotherwise secured together.

a a represent the transverse horizontal bars of the arch, which areprovided at each end with a casting b, to which are secured thedownwardly-extending pivots or standards, upon which the independentaxles are pivotally mounted.

a or represent forwardly extending bars of the main frame, bolted attheir rear ends to the forward bar a, extending forward substantiallyperpendicular to the said bar a for a considerable distance and thenbend inward and are secured pivotally to the tongue A at A a representsa continuous bar having its ends bolted to the arch-bar CL, its mainportions parallel with the bars a a'and provided with acentralportion (1which extends transversely of the machine immediately in rear of thetongue A. The parallel portions of the bars a and a are spaced by theblocks a and are united by bolts passing through said blocks.

a a represent inclined brace-bars, each of which is connected at itsrear end to the bars a a and at the forward ends to the bars a a tostiffen the frame.

Each of the end castings b b is provided on its under side with avertical recess or socket, in which is placed a vertical pivot-standardB, held in place by means of a set-screw b. Upon the pivot-standard Bispivotally mounted the casting B, which is provided with a sleeve orsocket b to fit over the lower end of the pivot-standard B, a horizontalsleeve b to receive the axle B and an inwardlyextending sleeve or socket5 which receives the inner end of the steering-lever B Thepivot-standard B is secured in the socket b by means of a pin b which issecured to the standard and projects therefrom through a horizontalslot 1) in the wall of the socket b to permit the desired swing of theaxle. The axle B is secured in its sleeve 6 by a setscrew H, whichpreferably extends up through the bottom of the sleeve. Thesteering-lever is secured in its socket b by a set-screw b5. Upon eachof the axles B is mounted one of the two supporting-wheels C C, and uponeach of the inwardly-extending steering-levers B B is secured anadjustable footpiece 13, provided with a collar b, which slips over theend of lever 13 and is secured by means of a set-screw b It will thus beseen that by loosening the setscrew b the footpiece can be adjustedtoward or from the pivotstandard and also around the lever B which is around bar, or by loosening set-screw b the lever and footpiece may beremoved altogether. The pivotal casting B is also provided with aforwardly-extendin g perforated bracket b, to which is rigidly secured aforwardly-extending arm d, to the forward end of which is pivoted thetransverse connecting-bar D, by means of which the simultaneous movementof the two pivot-axles is produced.

Near its forward end the mainframe is provided with a depending portion,to which the front ends of the two cultivator-sections are pivoted. Thisdepending portion consists, mainly, of the arched bar having ahorizontal part E secured to the under side of the bars a a of the mainframe by means of suitable clips e and having downwardly-extending armse, provided at their lower ends with outwardly projecting horizontalpivots 6 Upon each of the pivots e is mounted a sleeve 6, preferablysquare in cross-section,as shown in Fig. 10, and to this sleeve isbolted ahinge member e. The forward ends of each of thecultivator-sections F is provided with a hinge member f, which ispivotally connected to the hinge member a of one of said sleeves e by avertical pivot-pin f This construction allows each cultivator-section tobe swung laterally on the pivot-pin f and to be moved up and down uponthe pivot 6 as will be readily understood from the drawings. The head ofthe pivot-pin f is preferably provided with one or more slots orrecesses, through which passes an elevating and depressing arm G, theforward end of which is bent downwardly and provided with a widenedportion g, through which are passed the bolts e", which secure the hingemember e to the sleeve 6 By reference to Figs. 2 and 10 it will be seenthat by means of this 1ever G the cultivator-sections can be raised orlowered upon the pivotal connection with the pivot e. The main frame isprovided on each side with an operating hand-lever G, pivoted to theframe and provided with the usual ratchet and segment for adjusting it.To the lower end of each lever G is pivoted an elevating and depressingrod G which has its upperend flattened to engage the lever G andprovided with a series of apertures g g to receive the pivot g, by meansof-which it is connected to the lever G. By this means the connectionbetween the lever G and the rod G may be adjusted. The main portion ofthe rod G is ordinarily round, and its lower end passes through a sleeveg on a casting g, which is preferably formed separately from and boltedto the elevating and depressing lever G, although it is obvious that itmight be formed integral therewith, if preferred. Below the sleeve g therod G is provided with a pin g by means of which the lever G may beelevated, and the rod G is also provided with a coiled spring g,surrounding the same above the sleeve 9 having one end engaging saidsleeve and its other end engaging a col lar g which is retained inposition by a pin 9 passing through the rod G From this construction itwill be seen that an upward movement of the rod G will positively raisethe lever G and the cultivator-section, while a downward movement of therod G will lower the section intothe ground and hold it down with ayielding pressure, owing to the spring 9 which is interposed between therod G and the elevating and depressing lever G. By means of thehand-levers G G the operator can elevate either section out of theground or lower it into operative position and hold it so that it willcultivate at the desired depth.

In order to hold the two cultivator-sections at any desired distanceapart when the machine is used as a pivot-axle cultivator, I provide thefollowing-described mechanism, which mechanism may, however, be thrownout of operation and, if desired, removed from the machine when themachine is used as an ordinary cultivator and the sections steered bythe feet of the operator.

h h represent two vertical bars having their upper ends pivoted to thetransverse connecting-bar D at opposite sides of the center and theirlower ends passing through eyes or loops secured to thecultivator-sections, so that by giving these rods a simultaneous inwardor outward movement the cultivator-sections will be drawn closertogether or separated.

H represents a removable casting which is provided on its under sidewith a recess h, adapted to fit over the transverse connectingbar D, asclearly shown in Fig. 6, and to be secured thereto by a bolt h. Thiscasting H is also provided with a segment h, having a stop hi at itsupper and at its lower end and provided with teeth to engage the usualleverpawl, and said casting is also provided with a downwardly-extendingguide M, of a rightangular retaining construction analogous to adovetail. I

11 represents a verticallymovable slide having a recess to engage theguide It, and

said slide is also provided with lateral1y-extending arms it, having attheir outer ends curved slots h and preferably having on one side aseries of serrations or ribs h adjacent to the slotted portions.

h h represent adjustable links, each of which is connected at one endpivotally to one of the downwardly-extending bars h intermediate itsends and has its other end connected by a pivot-bolt 7L1 to the slide H.Each of the links it is provided with an adjusting bolt 7i, extendingthrough the same and through the slotted portion 71. of one of the armsh of the slide H, and said bolt is provided with a block 72 having itsinner face ribbed or serrated to engage the face it of said arm, thesaid bolt being also provided with the usual nut h. It will be seen thatwhen the nuts h are loosened if the slide H is moved up and down it willcause the bars h to move toward or away from each other, and therebyadjust the positions of the cultivator-sections. It will also be seenthat under these conditions the links 71 can be moved to differentangles with respect to the slide H, so as to give the proper or desiredmovements to the cultivator-sections. It will be further seen that theslide can be moved to bring the cultivator-sections nearer together orplace them farther apart and the nuts 72, then tightened to maintainthem in that relation, if desired.

II represents a hand-lever pivoted to the casting H at h and providedwith the customary spring-pawl for engaging the segment 76 The lever His connected by a link H with a pin h on the slide H, so that the slidecan be moved and held in any desired position by means of the lever andsegment. WVhen it is desired to use the machine as an ordinarywheel-cultivator and to steer the sections by means of the op'eratorsfeet, the links 72, it" can be disconnected from the rods or bars 7t andby removing the bolt 71 the casting H can be entirely removed from themachine, with all its connected parts. Each section is provided adjacentto its rear end with a loop or stirrup I (see Figs. 1 and 3) for thereception of the feet of the operator, so that the sections can besteered independ ently. In using the machine in this way it will benecessary to lock the axles, so that they shall hold the Wheels inposition to travel in a straight line, and in order to effect thisresult I provide the transverse connecting-bar D with a locking bar orlink D, provided with a locking-notch D adapted to fitovcra member ofthe frame of the machine, thereby locking the bar D and preventing anymovement of the axles with respect to the frame.

I also provide means for adjusting the tongue with respect to the mainframe of the machine,which is illustrated in detailin Fig.4.

K K represent two castings which are bolted to the forward transversebars a of the main frame on either side of the rear end of the tongue A.Each of these castings is provided with a footpiece 7a to engage the bara said footpiece having upper and lower flanges k to embrace said barand being provided with a hole preferably square, to allow thesecuring-bolts to pass through. Each of the said castings K is providedalso with a vertically-disposed guide-plate 70 having an inner smoothface to engage the tongue and an exterior serrated face 70 the saidplate 10 being also provided with a vertically-disposed slot k curved inthe arc of a circle, the center of which is represented by the pivotalconnection of the tongue with the main frame at a. A bolt K passesthrough the tongue I A and through the slots of the plates k it and isprovided on the outer side of both plates with a clamping-block 7c",having a serrated inner face to interlock with the serrations of theouter face of the adjacent plates k The bolt is also provided with a nut10 It will be seen that by loosening the nut 70" sufficiently to allowthe clamping-plate k to become disengaged from the serrations of theplates k the rear end of the tongue can be adjusted up or down to bringthe main frame of the machine in the desired position, and the parts canbe rigidly secured to the other by turning up said nut k all withoutremoving the bolt K.

The main frame is provided with a rearwardly-extending drivers seat Land with the usual draft appliances, the specific construction of whichforms no part of my present invention and need not therefore bedescribed in detail.

It will be observed that in my improved cultivator the elevating anddepressing lever G is not attached directly to the cultivator-sectioncontrolled by it, but is attached to the sleeve 6 forward of thevertical pivot on which the section swings laterally. Therefore eachcultivator-section when adjusted vertically can be swung laterally ineither direction without being raised or lowered. I believe this to bean entirely new feature in pivot-axle cultivator-s, and I claim itbroadly.
